But that's not all, the special will introduce Charlie Kersh as Min, the daughter of Trini Kwan, the original Mighty Morphin Yellow Ranger! Oh, and an Alpha is in the special as well. The last Alpha we saw was Alpha 6 in "Once A Ranger" in Power Rangers Operation Overdrive. Other details such as the plot and format will be revealed in a later date. The Power Rangers 30th Anniversary Special is set for a 2023 release.
